Gardevoir

At first sight, Alakazam and Uxie both seem to outclass Gardevoir, but it can distinguish itself by being offensive and defensive at the same time. Gardevoir has a vast support movepool, including options like Will-O-Wisp, Wish, Taunt, and Encore. Offensively, Gardevoir has base 125 Special Attack, along with a good offensive movepool to deal massive damage to incoming foes. Gardevoir also comes with the rare Trace ability, allowing it to copy an opponent's ability and turn the tables on them.

Gardevoir has a few problems to address, however. Due to it being a balance of offense and defense, this means it does not excel at either of these roles, and Alakazam or Uxie may be more suitable. As with Alakazam, Gardevoir has low Defense and HP stats, meaning that it is vulnerable to Pursuit-wielding physical attackers. Gardevoir's 80 base Speed is also rather average, allowing many other Pokemon to outspeed it. Nevertheless, Gardevoir's Trace ability, great movepool, and spectacular special stats all are advantages that make it unique.
